The Fractal Design Define XL R2 is built to be one tough case. The design behind the Define XL R2 is performance, silence, and with the option for more airflow and water cooling. Fractal is one of the only manufacturers to include high density matting in their system builds to reduce the vibration and noise, all unused fan mounting locations are also filled with their ModuVent system so the user can decide between more airflow or silence. The motherboard tray features support for ATX, Micro ATX, Mini ITX, E-ATX, and XL-ATX form factors. Plenty of cable management options are available on the Fractal Define XL R2, with rubber grommets all over the motherboard tray and tie downs on the back of the tray. The stock cooling system consists of three 140mm fans and four additional 120mm/140mm fans can be installed, along with plenty of mounting locations for water cooling using 240mm and 120mm radiators.
